SPECIFICATION forming part of Letters Patent No. 3 09,4100, datedDecember 16, 1884.

Applicalion lllod November 3. 18 34.

tors of reference marked thereon, to be a full,

clear, and exact description of the same, and which said drawingsconstitute part of this specification, and represent, in

Figure 1, a left-hand side view; Fig. 2, a

right-hand side view; Fig. 3, a longitudinal central section; Fig. 4, atransverse section on line :0 x of Fig. 1.; Fig. 5, a transverse sectionon line :2 z of Fig. 1.

This invention relates to animproveincnt in that class ot'joiners planeswhich consist of a cast-metal stock fitted with a clamping device tohold the cutter, and mechanism for adj ust ing the cutter with relationto the mouth, the object of the invention being to simplify theconstruction, so that the plane may be produced with very littlemechanical labor, and thereby greatly reduce the cost; and the inventionconsists in the construction, as here inafter described, and moreparticularly recited in the claims.

A. represents the base or plate of the stock, fitted at one end with ahandle, B, and may be at the other with a handle, C, and with the usualtransverse mouth, at, opening into the throat 1). Immediately in rear ofthe throat is a bearing, E, inclined to the position required for thecutter, and upon which the lower end of the cutter F may lie. Centrallyfrom this bearing 1G a lug, 0, extends upward, inclined corresponding tothe incline oi" the bearing-surface E.

G is the bed for the cutter. At its lower end it is constructed with arecess, (Z, upon its face side, corresponding, substantially, to the lugb, as seen in Figs. 3 and 5. The face of the cutter-bed G forms,substantially, acontinuation of the inclined bearing E, as seen in Fig.The upper end of the bed G is constructed with a groove upon its underside, to ride upon a guide, 0, formed 011 the handle portion above thebearing-surface 1D. The

groove is best formed by a rib or flange near each edge of the upperpart of the bed, to enibrace the bearing a, as seen in Fig. 4.

The

(No model.)

bed is constructed with a hook, f, upon each side near its lower end,these hooks formed by extending or turning the edge upward and in ward,as seen in Fig. 5.

H is the cap for the cutter, provided at its upper end with a set-screw,l. The hooks are ot'such extent that the cutter F may be set downbetween them and the bed, and then the cap H introduced between thecutter and the hooks, as seen in Figs. 3 and 5, the cap extending downtoward the ed go of the cutter, the screw taking its bearing upon thecutter above the hooks. Thus introduced, the screw is turned to abearing upon the cutter, forcing the cutter firmly against the bed G,and cansing the lower end of the cap to turn inward against the cutterand clamp the cutter upon the bearing E, as seen in Fig. 3, so as tofirmly secure the cutter in its place. The cap may be adj ustcd to anydesired relation to thecdge of the cutter, so that it may serve as thecap for the cutter to govern the depth of the cut,

if desired.

To adjust the cutter the bed G is constructed with a flange, it, uponone side of the handle portion, as seen in Figs.-l and 4. This flange isconstructed with a notch or opening, 2. Through the handle port-ion acoarse-threaded screw, L, is introduced, the handle portion beingcorrespondingly screw-threaded, as seen in Fig. This screw is providedwith an cecentric stud, Z, which stands in the slot 2' of the bed, andso that if the screw be turned to impart a crank-like movement to thestud Z, it will correspondingly move the bed G up or down, according tothe rotation of the screw E. Upon the reverse side the screw is providedwith a handle, M, by which it may be conveniently turned. Thescrew-thread on this adjusting device imparts a longitudinal movement tothe stud Z as the screw is turned, hence produces a transverse frictionbetween it and the surface of the notch in which it works, in additionto the friction which nating-stud Z. By this construction the stock isreadily molded and cast complete, the cleaning and preparation of thecasting to receive the cutter and bed being an inconsiderable operation.The bed G is also cast complete, ready for application to the stockwithout any material mechanical labor, and thus I produce a plane at aminimum cost, yet complete and perfect in its working and adjustment.

To prevent the possibility of the cutter being thrown out of adjustmentby contact with knots, or other extraordinary hard attacks in operation,I construct the face of the bed with a series of notches on its face,and provide the cutter with a corresponding stud, on, (see Fig. 3,) andso that when the cutter is set in place the stud may enter one of thenotches in the bed and there hold firmly, so that any adjustment of thebed must be necessarily imparted to the cutter, and the notch and studserve to resist any tendency of the work to throw the cutter out ofadjustment.

I claim l. The metal stock, constructed with the inclined bearing E inrear of its mouth, and with the lug Z) extending upward and backwardtherefrom, the bed G, constructed with a recess, (1, upon its face,corresponding to the said lug b, said bed also constructed with hooksff, and arranged to take a bearing on the stock above the said lug,combined with.

' the cutter F, cap H, and the set-screw I in said cap, substantially asdescribed.

2. The metal stock, constructed with an inclined bearing, E, in .rear ofits mouth, and with a lug, Z), extending upward and backward therefrom,the bed G, constructed with a recess, (2, corresponding to said lug, andarranged to take a bearing on the stock above, and also constructed withhooks f f, and with a downwardly projecting flange having a notch, t,therein, the cutter F, cap II, and setscrew I, with the screw Etransversely through the stock, said screw provided with an eccentricstud, Z, at one end to work in said notch i, the opposite end providedwith a handle, M, substantially as and for the purpose described.

3. The stockconstructed with the inclined bearing E in rear of itsmouth, and with the lug 0 extending upwardand backward therefrom, thebed G, constructed with a recess, d, corresponding to said lug, and alsowith hooks ff, the said bed arranged to take a bearing upon the stockabove the said lug b, the face of the said bed constructed with a seriesof notches, the cutter constructed with a stud, m, upon its underside toengage either of said notches, the cap H, and set-screw I, substantially as described.
